[Twisted-Python] FTP/VFS -- registerProducer error

[Kyle Johnson]

Modeling my code off the FTP server example
(http://twistedmatrix.com/trac/attachment/ticket/1579/ftp_server_example.py),
I coded my own FTPRealm class to use an inmem vfs instead of the local
filesystem.

I can browse and download data from it without issue, but anytime I
attempt to upload a file, I get this error:
File "twisted/protocols/ftp.py", line 421, in registerConsumer
    self._cons.registerProducer(self, True)
exceptions.AttributeError: _FileToConsumerAdapter instance has no
attribute 'registerProducer'


I'm setting up the avatar with the line:
avatar = FileSystemToIFTPShellAdaptor(pathutils.FileSystem(inmem.FakeDirectory()))

Full code is available here: http://rafb.net/p/FgTbiP80.html



Any help would be greatly appreciated.
